[NSA310S] Boot Debian USB + Boot ZyxelOS NAND? (7 replies)

Hello everyone! I have Zyxel NSA310S and I would like to be able to boot Debian from USB and start ZyxelOS when the USB flash drive is not inserted. I have read the 2 guides on Debian and Uboot but I can only boot Debian USB and went back to Uboot Stock. How do you recommend me to set it up? I am connected to the nas via Serial. A big thank you to bodhi!
